I am wondering if there are scientific studies to show at what period post op does the hormone Ghrelin start secreting

following a sleeve procedure and at what levels. Does it return to a preop level? I LOVE not being hungry!

Mine returned between year one and two after surgery. Was great while it lasted. It's tougher now fighting cravings and hunger urges to keep the weight off, then during the whole initial losing period.

I'm sure like everything relating to the body, each person's experience will be different. My advice is to really concentrate on solidifying your new healthly eating habits while you're losing. For me venturing off the path even a little resulted in weight gain. Gotta stick to the plan forever.

Here's the other revelation I found out after losing the weight........New studies seem to point to the fact that rapid large weight losses can change your body's metabolism pertinently.

That after you lose the weight by consuming so many fewer calories per day......your new maximum daily calorie intake for maintenance at your goal weight will be much less than normal. Mine dropped from 3000 calories a day, which was considered average for someone of my goal weight to about 1700-1800. Any more and I started to gain. Figures......we just can't catch a break.

Hey, it is what it is.......I save a ton on food. No regrets here.

According to the studies I linked, it drops to almost nothing day 1 post op, increases slightly at 6 months, and at 12 months is close to pre-op but not quite there. I am sure that by year 2 it is almost back to normal.

In one study there was one unlucky person that has higher levels post op than pre-op at 1 year.

Another thing that one study noted was the Sleeve and the Bypass have the same reduction levels. The band offers absolutely no ghrelin decrease at all.

I'm a year out and I still barely ever feel hungry and to feel hungry I have to go over 12 hours without eating, and at that point anyone would be hungry.

Where are you getting your BMR from? The average BMR for a 64 year old man at 185 pound is 1685, so your eating is right on target.

Where did you get 3000 from? That is the RMR of an obese person.

@@OutsideMatchInside - I haven't done any of the research on this, but I'm surprised the sleeve and bypass have the same affect on the hormone. I wondered about this because the stomach is still in there with the bypass. They aren't removing it like with the sleeve, so I thought the sleeve might have the upper hand with this.

Mine returned at 5 months. But not like preop. It just feels like a reminder that it's time to eat. It goes the minute I eat my first mouthful of food.

It was just one small study, but both surgeries has a hormone effect while the lapband has none.

Actually I'm 200 now, (my lowest was 185) And I'm not talking about RMR. That is based on doing nothing. I'm talking about metabolic rate and caloric intake based on my normal daily routine, which is quite active.

But regardless, those are just numbers. My point is I have to either work alot harder now to burn off the same calories others consume, or I have to eat less then they do to avoid gaining.

Have you had your RMR tested? I think I asked you before but I can't remember.

Thank you all for posting. It was just the information I needed.
